This document provides information on key concepts for graphing polynomial functions such as relative maximums and minimums, finding zeros of a function, and making tables of values to graph functions. It includes examples of making tables and graphs for the functions f(x) = -x3 - 4x2 + 5 and f(x) = x4 – x3 - 4x2 + 1. For the latter function, the document identifies that the zeros occur between -2 and -1, -1 and 0, and 0 and 1. It also shows working through an example to find the relative maximum and minimum values for the function f(x) = x3 – 4x2 + 5, identifying the relative max near x
